Privacy policy

1. Who processes the data

The data controller is the owner of the Chalkmoon service. For matters concerning personal data, write to kontakt@chalkmoon.com.

2. What data we collect

• Account data: full name, email address, a hashed password or a Google account identifier.
• Teacher profile, if you fill it in: subjects, grades, school type and additional information about your teaching. We add it to your conversations so the assistant does not ask for it every time.
• The content of conversations, created documents and uploaded attachments.
• Ratings of the assistant’s replies: thumbs up or down, the reasons you tick and your comment, if you add one.
• Technical session data: IP address, browser type, sign-in time.
• Model usage and web searches, converted into credits (to keep track of the daily limit and costs).

3. Students’ work

Attachments may contain students’ personal data. Before uploading a piece of work, remove the student’s name from it. If you upload students’ data, you do so as a teacher acting on behalf of your school and you are responsible for the basis for processing it.

4. Why we process data

• To provide the service: maintain your account, save conversations and documents, generate replies.
• To improve the assistant: we read your ratings together with the rated reply.
• To send messages related to your account: address confirmation, password change, account deletion.
• To protect the service against abuse.

We do not send advertising and we do not sell data.

5. Who we entrust data to

• Anthropic — provider of the Claude model. The content of the conversation and the attachments are sent to the model so that a reply can be generated.
• Web search — when the assistant checks something online, the search is run by Anthropic. The search engine receives a query that the model writes from the conversation. The assistant is instructed not to put students’ data in it. The pages found are stored with the conversation.
• Railway — hosting of the application, the database and files.
• Cloudflare — sending email messages.
• Google — only if you sign in with a Google account.

6. How long we keep data

We keep conversations, documents and attachments until you delete them. Deleting a conversation deletes its messages and attachments; you can delete its documents with it or keep them in My documents. Deleting your account deletes all your data. We delete ratings of replies together with the conversation.

7. Your rights

You have the right to access your data, to have it corrected or deleted, to restrict its processing and to have it transferred, as well as the right to lodge a complaint with the data protection authority in your country. You can delete your account yourself in the settings.

8. Cookies

We only use cookies that are necessary for signing in and for remembering your language, theme and time zone. We do not use advertising or analytics cookies.
